DESCRIPTION
xfhheater
Citation preview
FEATURESXfh gives you the ability to evaluate fired heater designs
and simulate the performance of existing fired heaters.
Independent modules for combustion, convection, radiant,
and API 530 calculations allow you to model individual
portions or the entire heater.
The graphical interface makes specifying your heater
extremely straightforward. And you can easily verify your
design or spot local performance problems using the
extensive output reports and graphing capabilities.
Xfh handles vertical cylindrical and single- or multicell box heaters and supports up to ten process fluids in convection section.
Hottel zoning in radiant section provides local predictions of heat flux and wall temperature.
Detailed output reports provide overall and localized results.
Extensive visualization tools show exactly how the heater is performing.
Integrated physical property system eliminates requirement for additional property generation software. Xchanger Suite includes VMGThermo, an extensive and rigorous fluid physical property generator, from Virtual Materials Group, Inc.
Xfh can import data from process simulators and physical property packages.
Both input and output support multiple unit sets, and custom unit sets can be defined.

CALCULATION FEATURES Rigorous process-side heat transfer and pressure drop calculations performed using an incrementation scheme to divide the flow path into a large number of zones
Process pressure can be specified at inlet, outlet, or radiant section
Single-zone model for simplified input or Hottel zoning option to calculate local heat flux and wall temperatures
Process heat transfer calculated using HTRI method, API 530/ISO 13704 method, or user-specified heat transfer coefficient
Radiant flue gas circulation calculations with jet similarity model
Independent modules for combustion, radiant, and convection sections allow modeling of one section or entire heater
No tubes option to model radiant section without specifying tube coil geometry
API 530/ISO 13704 TUBE DESIGN Tube design and tube life evaluated using API 530/ISO 13704 procedures
Required tube metal thickness and tube metal temperatures reported
Check for elastic or rupture limitations
Tube retirement tables can be used to determine optimum maintenance schedule
OUTPUT REPORTS Extensive set of spreadsheet-style output reports that can be printed or exported to Microsoft Excel
Summary reports with overall results in one or two pages
Detailed reports for local profiles of all important parameters (temperature, pressure, heat transfer coefficients, heat flux, etc.)
Standard API 560/ISO 13705 specification sheet
Selectable font sizes to make reports easy to view
Customizable unit sets that can be changed dynamically as you work
GRAPHIC VISUALIZATION 2D and 3D scaled drawings provide visual confirmation of heater geometry
2D and 3D plots of local performance variables allow you to quickly spot any performance issues such as high wall temperatures
